Many Businesses Fail To Disclose Data Breaches

There are likely many more breached retailers than Target, Neiman Marcus, Michaels, and Sally Beauty either unaware that they have been hit or not yet ready to go public. There also are many data breaches, even at retailers, that may never see the light of day: As a matter of fact, some 57% of organizations worldwide say they do not voluntarily report hacks that aren't bound by disclosure laws.

So says a new report published Tuesday by Arbor Networks and The Economist Intelligence Unit, which surveyed some 360 C-level or board-level business executives around the globe on their incident-response posture.

"Only a third of companies are willing to share information about incidents with other organizations ... But these days, the only way to defend is sharing," says Dan Holden, director of Arbor's ASERT.
